兔场消毒技术规范：消毒剂选择与轮换策略

Disinfection is the fundamental line of defense in rabbit farm biosecurity systems. Standardized disinfection procedures effectively cut pathogen transmission routes and reduce infection risk. However, disinfection is not simply spraying chemicals; it requires scientific planning and strict execution.

Common disinfectant classification: chlorine compounds such as sodium hypochlorite are effective against bacteria, viruses, and fungi but corrosive to metals. Iodine compounds such as povidone-iodine have broad-spectrum activity with low irritation. Quaternary ammonium compounds such as benzalkonium bromide are effective against bacteria but not spores. Aldehydes such as glutaraldehyde are most potent but irritating to humans and animals.

Different zones use differentiated disinfection protocols. Production areas: spray disinfection with rabbits present 2-3 times weekly using low-irritation iodine or quaternary ammonium compounds. Empty housing disinfection uses aldehyde or peracetic acid fumigation, sealed for 24 hours then thoroughly ventilated.

Disinfectant rotation is key to preventing microbial resistance. Rotate disinfectants with different mechanisms every 3 months. Recommended rotation: quaternary ammonium → iodine → chlorine → aldehyde. Never mix different disinfectant types arbitrarily.

Disinfection operation standards: clean to remove organic matter before disinfecting, as organic matter severely impacts efficacy. Prepare disinfectant solutions fresh before use; ensure contact time no less than 30 minutes. Conduct disinfection efficacy testing quarterly using ATP bioluminescence or bacterial culture methods.
